San Giusto a Rentennano

San Giusto a Rentennano takes its name from Etruscan origins and began life as a medieval monastery of Cistercian nuns, known as San Giusto alle Monache (of the Nuns). In 1204 it was fortified by the Florentines after a treaty established it as the boundary with Siena. Portions of the ancient fortification still stand, with the underground vaults now serving as the estate's aging cellars. The Ricasoli family, of Brolio and Chianti fame, presided over the estate for several centuries before it passed to the Martini di Cigala family through marriage in 1914. Enrico Martini di Cigala inherited it in 1957, and in 1992 his nine children became heirs. Today, Anna, Lucia, Elisabetta, Francesco, Alessandro, and Luca are partners, with Elisabetta, Francesco, and Luca handling day-to-day management.

• Enrico Martini di Cigala inherited in 1957; nine children inherited in 1992; Elisabetta, Francesco, and Luca now manage operations with consultant oenologist Attilio Pagli (since 1999) and agronomist Ruggero Mazzilli (since 2007)

San Giusto a Rentennano occupies 160 hectares in Gaiole, the southernmost commune of Chianti Classico, with 31 hectares planted to vines at an average altitude of 270 metres above sea level. The estate overlooks the Arbia River to the west. Soils in the Percarlo vineyards are dominated by Pliocene-epoch deposits: layers of sand and stones two to five metres deep resting on clay beds, a profile that imparts the wines' characteristic mineral precision. The microclimate features pronounced diurnal temperature variation, which preserves natural acidity in the grapes. All 31 hectares have been managed organically since 2001 and hold organic certification since 2006. A green harvest is carried out each July and August, reducing the natural yield by 20 to 50% to concentrate the remaining fruit. All grapes are hand-picked.

• Elevation averages 270 metres above sea level in Gaiole, the southernmost commune of Chianti Classico; dramatic diurnal temperature shifts enhance acidity and aromatic freshness
• Percarlo vineyard soils: Pliocene-epoch layers of sand and stone (2-5 metres deep) over clay beds; tufaceous and sandy elements across the broader estate
• Organically managed since 2001, certified since 2006; green harvest in July-August reduces yields by 20-50%; all grapes hand-picked

Winemaking at San Giusto a Rentennano is built on indigenous yeast fermentation, careful maceration, and oak regimes calibrated to each wine's character. The Chianti Classico is fermented in glazed concrete and stainless steel vats for approximately 14 days, then aged in 500-litre tonneaux for 10 to 12 months. The Riserva Le Baròncole follows an extended 16 to 20 months in French oak, with an additional six months in bottle before release. Percarlo receives the most rigorous treatment: grapes are selected bunch by bunch from the estate's finest zones, fermented and macerated in vitrified concrete vats for up to 35 days with indigenous yeasts, then aged in 225-litre French oak barriques for 20 to 22 months, followed by 15 months in bottle before release. The estate will decline to produce Percarlo in vintages where fruit quality does not meet its standard, as occurred in 2000 and 2002. La Ricolma undergoes an identical oak regime to Percarlo: 22 months in 225-litre French oak barriques.

• All fermentation with indigenous (natural) yeasts; Chianti Classico: approximately 14-day maceration in steel and glazed concrete, 10-12 months in 500-litre tonneaux
• Riserva Le Baròncole: 16-20 months in French oak, plus 6 months bottle aging before release
• Percarlo: bunch-by-bunch selection, maceration up to 35 days in vitrified concrete, 20-22 months in 225-litre French oak barriques, then 15 months bottle aging; not produced in sub-standard vintages

The estate produces five wines. The Chianti Classico DOCG, approximately 95% Sangiovese and 5% Canaiolo, is the accessible, food-centric expression of the estate's terroir. The Chianti Classico Riserva Le Baròncole, at 97% Sangiovese and 3% Canaiolo, is drawn from selected parcels and offers greater complexity and age-worthiness. Percarlo, the flagship, is a 100% Sangiovese Toscana IGT that debuted in 1983 and is selected bunch by bunch from six parcels of the estate's best Sangiovese vines, with production of around 1,600 cases per year. La Ricolma, a 100% Merlot Toscana IGT first produced in 1993, is grown in five dedicated plots and has become one of the most sought-after Merlots in Tuscany. Vin San Giusto, the estate's passito bianco (90% Malvasia, 10% Trebbiano), is dried for 140 days and aged six years in small chestnut and oak barrels, resulting in an intensely concentrated sweet wine released in 375ml bottles.

• Chianti Classico DOCG: approximately 95% Sangiovese, 5% Canaiolo; fermented in steel and glazed concrete; 10-12 months in 500-litre tonneaux
• Chianti Classico Riserva Le Baròncole: 97% Sangiovese, 3% Canaiolo; 16-20 months French oak plus 6 months bottle; ages 15+ years
• Percarlo (1983 debut): 100% Sangiovese, Toscana IGT; approximately 1,600 cases/year; not produced in weak vintages; La Ricolma (1993 debut): 100% Merlot, Toscana IGT; five dedicated plots, clone 181

The Chianti Classico expresses pure, cool-climate Sangiovese: bright cherry, violet, mineral salinity, dried herb, and fine-grained tannins with crisp acidity. Riserva Le Baròncole moves toward darker fruit, flowers, spice, and licorice, with firmer tannin structure building complexity over a decade or more. Percarlo is the estate's most concentrated and complex expression: black cherry, cedar, tobacco, violet, and spice, always underpinned by Sangiovese's characteristic savory backbone, high acidity, and firm tannins that soften beautifully over 15 to 20 or more years in fine vintages. La Ricolma takes a different direction entirely, with dark plum, mocha, spice, and silky, supple texture that reflects Merlot's character filtered through Chianti's higher-altitude minerality and acidity. All wines reward cellaring, with even the estate Chianti Classico capable of evolving gracefully for a decade.

• Chianti Classico: bright cherry, violet, mineral, dried herb; crisp acidity; fine-grained tannins; food-forward style
• Riserva Le Baròncole: dark cherry, flowers, spice, licorice; firm structure; evolves well over 10-15 years
• Percarlo: concentrated black cherry, cedar, tobacco, spice; high acidity; ages 15-20+ years; La Ricolma: dark plum, mocha, spice; silky tannins with characteristic Chianti acidity and minerality

San Giusto's wines are quintessentially food-driven, shaped by the high natural acidity and structural tannin that Gaiole's soils and climate reliably deliver. The Chianti Classico pairs naturally with ribollita, pappardelle al cinghiale, pasta with tomato-based sauces, and aged pecorino. Riserva Le Baròncole demands more serious partners: bistecca alla fiorentina, roasted game, porcini risotto, and aged hard cheeses. Percarlo, with its density and savory complexity, shines alongside duck breast, truffle-based preparations, wild boar, and umami-rich braised dishes. La Ricolma, with its plush Merlot character tempered by Tuscan acidity, pairs well with lamb, herb-crusted beef, and dishes with Mediterranean spice. Collectors prize Percarlo and La Ricolma for their consistent critical acclaim, tiny production, organic farming credentials, and relative undervaluation compared to Brunello di Montalcino at similar quality levels.

• Chianti Classico: ribollita, pappardelle al cinghiale, tomato-based pasta, aged pecorino or parmigiano
• Riserva Le Baròncole: bistecca alla fiorentina, roasted game, porcini mushroom risotto, aged hard cheeses
• Percarlo: duck breast, truffle preparations, wild boar ragu, braised beef; La Ricolma: herb-crusted lamb, braised short ribs, Mediterranean-spiced red meat dishes
